A dark hall floor of hexagonal panels with glowing edges. Twelve agents type at red holographic consoles; one has turned white and raised a hand, and a beam of white light rises over it.

See the team you are directing.

Beamhall puts every Claude Code agent you run in herdr into one 3D office: what each is doing, what it costs, and when it needs a decision from you. Run them from your Mac or your phone.

Watch the trailer How it runs today

A dozen agents are running. Every one looks busy.

One of them is stuck, waiting on you. Which one?

The whole idea in half a minute.

Real app footage with simulated agents. It has narration and music, and it never plays on its own.

Directing agents is no longer writing code.

It is coordinating a team you cannot see. Beamhall is the room where you see it, and where you run it.

  1. The whole team, at a glance

    Every Claude Code agent you run in herdr is a character at a console that shows its real terminal output, grouped by project. Colour and pose tell you who is working, who is idle, who is done and who is waiting.

    The office from above: a ring of floor for each project, with agents at their consoles and small labels with their names and states.

  2. What each one is doing, and what it costs

    Open an agent and its session is there as a conversation, streaming while it writes. Beamhall also shows its model, how full its context is, and an estimate of what it has spent at API list prices (not your bill).

    The office on the left and a side panel on the right with the conversation with the agent harbor-2, its live output and a message box. The top bar shows a cost total, counters and a search button.

  3. The beam, when one needs you

    When an agent stops to ask you something, it turns white and a beam of light rises over it. You find it from the far side of the office, or jump straight to it with the space bar.

    A tall white beam of light over one agent, far across the dark office, labelled harbor-2 needs you.

  4. Answer, and keep directing

    Pick from the same options Claude Code is offering; the ones that widen its permissions are marked in amber. From the same place you send messages, start, resume and end agents, and switch the model of one that is idle.

    A permission request for the command npm test with three numbered answers; the one that widens permissions is outlined in amber.

  5. From the Mac or the phone

    On the Mac the office opens in its own window. On your phone the same agents are a list of cards with the one that needs you on top, over your home network or over Tailscale.

    The same office in a Mac window and on a phone, where the agent that needs you has a Respond button.

Under the office, one small server.

The 3D is the surface. Behind it a single Node.js process with no npm dependencies reads herdr and each agent's Claude Code session, and keeps the office up to date.

The phone view: a list of agent cards. The first one, harbor-2, needs you and has a Respond button; the rest are working.
State
Working, idle, done or needs you, for every agent, with the title of its session.
Model and context
Which model each agent runs and how much of its context window is in use.
Cost
Tokens priced at API list prices, per agent and for the day. An estimate, not your bill.
Machine
CPU, memory and disk of the Mac, and the CPU and memory each agent takes.
Getting around
A tab for each open agent, a mark on replies you have not read, arrows to move between agents and projects, search across every session.
Around the agents
Git changes per project, quick commands, shell terminals, and notifications in the app and on macOS.

Every screenshot on this page comes from the real app running simulated agents, with made-up project names and figures.

A prototype, used daily.

Beamhall is a spike that proved the idea. It works on its author's Mac every day, and it is not a finished product.

Expect rough edges and breaking changes. There is no installer to download, no support promise and no license yet.

Runs on
macOS, the only platform tested
Needs
Node.js 22 or newer, herdr, Claude Code and git
Phone
Off by default. Works over your home network, or over Tailscale for devices you mark as trusted. A connected phone can do everything you can do at the Mac.
License
To be decided. All rights reserved for now.

How it runs today

Beamhall runs from its source code with Node.js, next to herdr. Nothing to build, no packages to install.

The source is not public yet. When it is, the link will be here. Until then, the trailer is the best way to see it.
Watch the trailer

  1. Have herdr running, with your Claude Code agents started inside it.

  2. From the Beamhall folder, start the server.

    node spike/server.mjs

  3. Open the office in your browser. It listens on this Mac only.

  4. Optional: keep it running in the background and get a Beamhall app with its own window.
